Consider the following statements regarding the physical geography of Tamil Nadu: 1. The Western Ghats within Tamil Nadu are breached by the Palghat Gap, which facilitates moisture-laden monsoon winds into the interior plains. 2. The Nilgiri Hills form a major mountainous knot where the Eastern Ghats and Western Ghats converge. 3. The Cauvery Delta region constitutes the primary fertile alluvial granary of the state. Which of the statements given above are correct?

💡 Solution & Explanation

The Palghat Gap is a major low mountain pass in the Western Ghats located on the border of Kerala and Tamil Nadu, easing climatic and transport connectivity. The Nilgiri range acts as the junction point where the Eastern and Western Ghats meet. The Cauvery Delta in the eastern plains forms the core agricultural zone supported by extensive irrigation networks. Tamil Nadu receives substantial rainfall from the retreating northeast monsoon in addition to the southwest monsoon.
